I recently picked up XWA again after many years of inactivity. I recall there being a sort of simulator or obstacle course (rings that speed you up when you go through them). does this sound familiar to anyone? I have been through the combat simulator, but have not been able to find it. The only thing I can think of is that it is an option only available after reaching a certain point in the game. Anyone have any insights?

ok, I found it. it is not available until you meet up with the rebels in "joining the rebellion"
